Analog Feedback Amplifier Design
$30-250 USD
Paid on delivery
I am looking for someone to update an existing feedback amplifier design. The existing design is a simple opamp circuit that takes a +/- 10 Vdc input and applies a gain of 0.1 to 1.0. The existing circuit also has the ability to be changed from inverting to non-inverting using jumpers to configure the OP-amp input. The circuit schematic for the existing is available. Also in addition the new design would have an integrated 24 Vdc to +/- 15 Vdc power supply. The existing circuit uses an external +/- 15 Vdc power supply.
The end result of this project would be a circuit that provides the same gain amplifier and has the following additional features:
- Option for user to select between internal 24 Vdc to +/- 15 VDc power supply. The power supply selection between Internal and External (A,B,C) can be accomplished with jumpers. Example, if internal supply then use jumpers to connect supply output to pins A, B, C.
- solid state fuse / circuit breaker to protect +/- 15 vdc power that goes off of board (50 ma, on diagram this would be F and H).
